It is also the principal cement used in most masonry mortars and renders. The most commonly used type of Portland cement is Ordinary Portland Cement (OPC), but there are other varieties available, such as white Portland cement.

	Cement is a substance used for binding and hardening other materials. Water and cement set and harden through a chemical reaction known as 'hydration'. The process of hardening is described as 'curing', and it requires particular conditions of temperature and humidity.		Cement is a substance used for binding and hardening other materials.

	The quarried material is then crushed, first to reduce it to a maximum size of approximately 6 inches, and then to about 3 inches or less using secondary crushers or hammer mills. The crushed rock is then ground, mixed and fed into large rotary kilns, which heat it to approximately 2,700ºF (1,500 Celsius). Coolers are used to bring down the temperature of the clinker, before cement plants grind and mix it together with small amounts of gypsum and limestone. Once this is done, it can be packaged and sold for use in construction.
